Scene looks darker when playing

Hi, I made a simple scene with an ocean in it. In the editor window, the scene looks bright and vibrant, but when I press the play button, it suddenly becomes a lot darker and dull looking. I’ve checked the exposure, and it’s not causing this issue. Also the post processing is set to unbound.
It seems as if the reflection is mostly gone once I play the game. Does anyone know what exactly is causing this and how to fix it? There are no reflection sphere captures as this would mess with the horizon.

Oh never mind. Apparantly a reflection sphere was hidden somewhere in the scene. I got rid of it, and now everything is fine.
